Agreed, but this is how I broke in my engine and it runs great:http://mototuneusa.com/break_in_secrets.htm
I sent the oil to a test lab for analysis after 1200 miles (http://www.blackstone-labs.com/index.html) and it came back with normal results.
So, you can put me in the fast break in side of the discussion.

Out of curiosity what is the general time limit on breaking in a motor. What I mean is I hear of some never seating the rings and screwing up things. Also I am sure you have to idle for a while while checking for leaks adjusting things ETC. Just thought I would throw this out there. I have always agreed with the mototuneusa page.

The old 1500-2000rpms to break in FLAT TAPPETS is contrary to what it takes to really seat rings well. People would do well to try and understand things occassionally. The 1500-2000rpms thing was specifically for breaking in flat tappets.
Given the number of us that reuse original lifters at cam swap time I have to say that there is no wear pattern to worry about with roller lifters, sure there will technically be a "wear pattern" but not anything we need to be concerned with.
